Was poking around the St. Pets site looking for some info I needed and found this page that has MP3 tracks from their performance of Handel's Messiah last November. Pretty good stuff. I was disappointed that I wasn't able to go to the performance but Oh! the wonders of the Internet.

As a warning, in the background you'll hear pews creaking, feet shuffling, and an occasional baby babbling. So if that'll bug you, don't bother.
